• <p>操作符表:</p>

Order Name Representation
--- --- ---
1 成组 ( )

2 成群 ? + * {m,n} {m, n}?

3 锚点 abc ^ $

4 或

5 取组 $0-$9

字符表:

• 几个例子:

=regex("Peter Gordon: some@email.com, 47", "w+@w+.w+")

=regex("Peter Gordon: some@email.com, 47", "w+@w+.w+", "$0")

Results in: some@email.com

=regex("Peter Gordon: some@email.com, 47", "^(.+): (.+), (d+)$", "E-Mail: $2, Name: $1")

Results in: E-Mail: some@email.com, Name: Peter Gordon

=regex("Peter Gordon: some@email.com, 47", "^(.+): (.+), (d+)$", "$" & 1)

=regex("Peter Gordon: some@email.com, 47", "^(.+): (.+), (d+)$", "$" & 2)

Results in: Peter Gordon some@email.com .
